Blueair quality, genuine performance
Unlike generic look-a-likes, this genuine Blueair replacement filter is specifically designed to maintain premium performance over time.
The ComboFilter does not only have a particle filter, it also contains carbon particles integrated throughout the filter media to effectively remove fine particles, dust, gas and VOCs from the air. There are two filters, placed each at the top and bottom of the air purifier to ensure optimal removal. The electrostatic charged particles stick to the filters efficiently, and the activated carbon integrated in the filters adsorbs any odors and gases.
HEPASilent Technology™
Blueair’s HEPASilent™ filtration process captures 99.97% of airborne particles down to 0.1 micron in size. HEPASilent technology unites the best in electrostatic and mechanical filtration. Its revolutionary combination of advanced filter media and an encapsulated ion particle charging chamber ensures that your Blueair purifier delivers results far superior than either mechanical or electrostatic technology alone.
Removes pollutants and allergens
Independently verified to remove allergens like dust, pollen, mold, pet dander and more.
Effectively removes chemicals, VOCs and odors
Integrated with activated carbon throughout the particle filter, which effectively removes chemicals, gases, VOCs and annoying household odors from the air.
Double-filter for optimal removal
The ComboFilter doesn't only have a particle filter, it also contains carbon particles integrated throughout the filter media to effectively remove fine particles, dust, gas and VOCs from the air. There are two filters, placed each at the top and bottom of the air purifier to ensure optimal removal.
Naturally antibacterial
The naturally antibacterial polypropylene fibers in Blueair filters prevent bacteria and mold growth, so our filters never put bacteria and mold back into the air.
Whisper silent
Due to the use of both electrostatic and mechanical filtration, the filter media in Blueair filters is less dense than comparable media. Lower density enables air to move through the filter at a lower pressure, so you get high performance with a whisper-silent delivery of clean air.
Up to 1 year filter lifetime
The ComboFilter can last to a maximum of one year, depending on room conditions. When it's time to replace the filter, the Blueair app will send you an alert and allow you to re-order at the touch of a button.
Charged pre-filters
Positively charged pre-filters act like a magnet, attracting the negatively charged dust particles. The pre-filters are cleanable, which conveniently pop-out for quick maintenance and cleaning, to significantly extend the lifetime of the main filter.
